Topic tags/keywords: question router bits sharp

Personally, I think my garage is built over the site of an ancient power tool burial ground. Or perhaps I have an infestation of workshop gremlins. I’ve advanced both of these theories to my friends at the local Rockler, and they say it’s more likely to be “operator error.” Whatever the cause, I can’t seem to make a router bit last more than a week of making box joints before it starts getting uncooperative and chewing up large chunks of wood. What are the “best practices” for being nice to your router bits and making them last?

-- - Jei, Rockford IL - When in doubt, spray it with WD-40 and wrap it with duct tape. The details will attend to themselves.

No expert, but all can think of.
1) pull the nails and screws out first. :-)
2) keep the heat down with smaller passes. Heat is enemy of bits.
3) Naturally, keep bottom of bit 1/8” above collet.
4) wet end grain for less tear out and may help with heat.
5) use right speed

One other thing to keep in mind is if you have a fairly good quality bit some profiles can be sharpened. A fellow in my area will sharpen them for much less than the price of a new one.

The suggestions above are very good regarding taking small bits and keeping them cool. I’ve had quite a few router bits that got dull very quickly and a few that seem to stand up to the test of time. There seems to be a definite correlation between the quality/price of the bit and how well it holds up. For what it is worth, I have found that Freud bits hold up the best for the long term.

They’re carbide, made by Rockler. I’m a bit worried about getting them sharpened because I use them for box joints. How much smaller does sharpening generally make a straight bit?

It might be time to consider an upgrade….Freud (as mentioned), Whiteside, Infinity, Eagle America, CMT, Amana, Katana….

keep them clean, and make small passes, on the sharpening note I use a flat folding diamond hone from lee valley tools for my router bits(carbide) all you need to do is make light passes on the flats of the bit(clean bit), and bob’s your uncle youre done, they usually end up sharper than when initialy purchased.

Correct sharpening of a bit doesn’t remove material in a way that reduces the diameter of the bit. The operative word, of course, is “correct”. – lol
